Whatever the case was, singer/actor Justin Timberlake and sexy hardbody actress Jessica Biel seemingly put the “on” in on-again, as they took a bike ride in Toronto, Canada on Saturday in these just-released photos obtained by RadarOnline.com.

The Southerner who brought sexy back — who’s also dated A-list talent the likes of Britney Spears and Cameron Diaz — was reportedly split with Biel, as their reps confirmed they were no longer together just four days ago.

These pics, however, will surely keep the rumor cycle (actually, bicycle) spinning.
